For the first time, scientists have demonstrated that negative refraction can be achieved using atomic arrays - without the need for artificially manufactured metamaterials. Scientists have long ...

Interactions between atoms and light rule the behavior of our physical world, but at the same time, can be extremely complex.

Optics and photonics are central to many aspects of our lives. Refraction, emission and absorption of light within materials govern imaging, sensing, lighting and communications. However, many of ...

Light transport simulation and rendering techniques form the backbone of modern computer graphics, enabling the creation of photorealistic images by accurately modelling the behaviour of light in ...
